1988 jeep yj cant shift into 4wd

i cant get my jeep to shift into 4wd. when i look under the jeep at the linkage while some one trys to move the shifter the linkage seems to get stopped or jammed. the shifter moves and then stops about a inch before it usually goes when shifting into 4wd like its hitting a wall or something. where could i start to look to resolve this problem?
Thanks

To me it sounds like it is binding up. Liberally soak all of the the linkages with PB blaster, or Kroil and let it work in for a hour or so. Also unbolt the inner and outter shift boots to ensure they are not jamming it up. Sometimes I need to have my XJ rolling forward a little to get my shifter for 4wd to engage or disengage

Sounds like the linkage has slipped. There is an adjustment procedure.

So a new bolt and filled the fluid I know there is going to be some damage to the Tcase but a replacement is not in the budget at the moment. On the plus side the Tcase works better then it ever has in the past for me but only owned the jeep for a short while.

Going to do tranny fluid change as soon as I can find a extension that I can grind down to fit the drain plug.

A 5/16" allen wrench works well. Only needs a tiny bit of grinding.
